What the answer to this question

The distance from the Earth to the moon is about 239,000 miles. Rewrite the distance in scientific notation.

egoroff_w [7]

Answer:

2.39 x 10^5 miles

Step-by-step explanation:

Although it is not usually written, there is always a .0 at the end of a number unless there is a specific decimal that was given.

So, the number here is 239,000.0 and if you count the number of spaces that the decimal needs to move in order to be in the correct spot for scientific notation (which is always after the first number), there is 5 spaces.

Therefore the answer is 2.39 x 10^5 miles.

What are the roots of the equation 16x² + 16x + 5 = 0 in simplest a + bi form?

Greeley [361]

Answer:

Below in bold.

Step-by-step explanation:

Using the quadratic formula :

roots = [-16 +/-√(16^2 - 4*16*5)] / (2*16)

= -0.5 +/- √(-64) /32

= -0.5 +/- 8i/32

= -0.5 + 0.25i and -0.5 - 0.25i

A sculpture is in the shape of a square pyramid. The sculpture has a height of 36 feet and a volume of 19,200 cubic feet. Find t

lorasvet [3.4K]

$Hello$ $Human!$

$The$ $answer$ $to$ $this$ $is$ :

$a = 40$ feet

<h2><u>EXPLANATION:</u></h2><h2><u></u></h2>

<u></u>

Given:

V = 19,200 feet³ volume of the sculpture

H = 36 feet height of the sculpture

a = ? side length of the square base

The formula for calculating the volume of a pyramid is:

V = B H / 3 ⇒ B = 3 V / H

B = 3 · 19,200 / 36 = 19,200 / 12 = 1,600

B = a²

a² = 1,600 ⇒ a = √1,600 = 40 feet

a = 40 feet

Mo’s farm stand sold a total of 165 pounds of apples and peaches. She sold apples for $1.75 per pound and peaches for $2.50 per

9966 [12]

Answer: 65 pounds of Peaches were sold.

Step-by-step explanation:

Let the number of pounds of Peaches sold = X pounds

Therefore the pound of apple sold = (165 - X ) pounds

Total pounds of apple and peaches sold = 165 pounds

Sale made on Peaches at the cost of $2,50 per Peache = $2.50X

sale made on apple sold at the cost of $1.75 per apple = $1.75(165 - x )

Total sale made on the sale of both Peaches and apple = $337.50

Therefore , open the bracket, add everything together and equate to the total sale made which is $337.50

we now have

2.50x + 1.75( 165 - x ) = 337.50

2.50x + 1.75 x 165 - 1.75x = 337.50

2.50x + 288.75 - 1.75x = 337.50

collect like terms

2.50x - 1.75x = 337.50 - 288.75

0.75x = 48.75

divide through by the coefficient of x which is 0.75

x = 48.75/0.75

= 65pounds .

Therefore, Mo's farm sold 65 pounds of Peaches.

Check ;

65 x 2.50 = $162.5

subtract 65 from 165 to get the pound of the appel

165 - 65 = 100 pounds of apple was sold.

now multiply 100 x 1.75

= $175

Now add the two together to give the total sale ,

$162.5 + $175 = $337.50.

Let f(x)=x3(exponent)+kx2(exponent)+x+5

When f(x) is divided by (x+2) the remainder is =3

This is the remainder theorem
